Improvement in weather-strips



UNITED STATES NELSON JOHNSON, OF JASPER, NEW YORK.

IMPROVEMENT IN WEATHER-STRIPS.

Specification forming part of Letters Patent No, 157,836, dated December15,1874; application tiled April 29,1874.

To all whom it may concern:

Be it known that I, NELsON JOHNSON, of the town of Jasper and county ofSteuben, in the State of New York, have invented an ImprovedWeather-Strip and Stop-Bead for Windows, of which the following is aspecification:

rlhis invention relates to adjustable weather-strips of that form inwhich a strip of elastic material is supported and adjusted by means ofa metallic holder in the form of a thin molding, and to thosewindow-beads which are made elastic or adjustable, so as to retain thesash at any desired height without the aid of sash-holders.

The present invention consists in a compound elastic strip or bead ofpeculiar construction, adapted to be applied in place of the ordinarystopbead, and to perform the functions of a stop-bead, weather-strip,and sash-holder in a superior manner.

A very narrow strip or cord of elastic material is employed, and it issecured and adjusted by one and the same set of ordinary wood-screws,and may readily be removed when worn out.

The invention is applicable to all windows in which sliding sashes areemployed.

Figure 1 is a face view of a car-window illustrating this invention.Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal sectionon the line 3 3, Fig. l. Figs. 4 and 5 are, respectively, a transversesection and a fragmentary side view of the strip or bead proper on alarger scale. Fig. 6 is a transverse section, representing a preferredmodification. Fig. 7 is a transverse section, representing anothermodiiication. Figs. 4to 7 are drawn on the same scale.

Referring to Figs. 1,2, and 3, A A represent portions of the wall of arailway-car; B, a window-frame therein; O, a xed upper sash; D a slidinglower sash, and E E improved strips or beading attached to the frame bycommon wood-screws z in place of the ordin ary stop-beads.

The improved strips or beads serve to form the guides for the slidingsash, and to keep the same tight, so as to exclude wind, rain and dust,and to prevent rattling, and to support the opened sash in any desiredposition. They are arranged at the bottom and sides of the sash; and mayeither be extended upward above the top of the sash, as represented, ormay take the place of the ordinary beads only to the height of theclosed sash; or short sections may be attached to the ordinary beads,the latter serving as the extended guides.

The improved strip or bead consists of a metallic holder, y, in the formof a light and thin molding, and a narrow strip or string, x., Ofindia-rubber or other elastic material. For the reception of the elasticmaterial a longitudinal recess is formed in or at the inner edge of theholder, and conformed to the general shape of the strip or cord ofelastic material. The holder is also perforated to receive the attachingscrews z, by adjusting which the recess ofthe holder is contracted orexpanded, and the elastic material is thus caused to project more orless, as required, in order to properly tighten and hold the sash.

The holder maybe made of sheet brass or other suitable metal, plain ordecorated, and the details of its form and construction are variable.

rI he holder is double, its two members being united along one edge, andthe two members may be interlocked 5 but, preferably, they are formed inone part, and adapted to spring apart, so as to facilitate releasing theelastic strip for renewal. Also, a properlybent plate, w, is preferablyarranged within the holder to form a solid back behind the elasticstrip, clos ing` the space between the members of the holder, asillustrated in Fig. 6, so as to confine the projection of the elasticmaterial to the side adjoining the sash.

The elastic strip is shown in two forms, round and square incross-section. It may also be of octagonal or other shape; but the twoforms of holder represented will probably answer for any form of stripwhich may be desired.

The strip, when worn on one face or corner, may be released and turned,and, when worn out, it may readily be replaced.

The device is adapted to be cheaply manufactured and readily applied,and possesses, also, the advantages of simplicity,compactncss, andneatness of appearance.
